Player will not Move

Hello Community.
I am new here an will learn to Programming Games.

I have look a Tutorial about Movement like Diablo.
Script works fine i think, but my Charakter dont move if i click on the ground.

Here my script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class ClickToMove : MonoBehaviour
6. {
7.     public float speed;
8.     public CharacterController controller;
9.     private Vector3 position;
10.    
11.     void Start()
12.     {
13.         position = transform.position;
14.     }
15.  
16.     void Update()
17.     {
18.         if(Input.GetMouseButton(0))
19.         {
20.             locatePosition();
21.         }
22.     }
23.    
24.     void locatePosition()
25.     {
26.         RaycastHit hit;
27.         Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
28.        
29.         if(Physics.Raycast(ray, out hit, 1000))
30.         {
31.             position = new Vector3(hit.point.x, hit.point.y, hit.point.z);
32.             Debug.Log(position);
33.         }
34.     }
35.    
36.     void moveToPosition()
37.     {
38.         if(Vector3.Distance(transform.position, position)>1)
39.         {
40.             Quaternion newRotation = Quaternion.LookRotation(position-transform.position, Vector3.forward);
41.            
42.             newRotation.x = 0f;
43.             newRotation.z = 0f;
44.            
45.             transform.rotation = Quaternion.Slerp(transform.rotation, newRotation, Time.deltaTime * 10);
46.             controller.SimpleMove(transform.forward * speed);
47.         }
48.     }
49. }
50.  

I use Unity 2018
The Tutorial where i have the script are this:
